OF INDIANAPOLIS, INDIAN A.

GONG.

SPECIFICATION formingpart of Letters Patent No, 692,149, dated January 28, 1902.

Application filed Februarylfi, 1901. Serial No. 47,522. (No model.)

To all whom it may concern:

Be it known that I, ANTHONY F. KLEIN- SCHMIDT, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Gong; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like characters refer to like parts.

The object of this invention is to improv the construction of gongs for door-bellsor any other kindred use, whereby the bellhammer continues to ring the gong for some time after power has been applied to the devlce.

The chief feature of this invention consists in actuating the bell-hammer by the reciprocation of a rack-bar moved in one direction by a push-button or equivalent and in the other direction by a spring and which actuates the bell-hammer in both its forward and backward movement.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a central section of the device mounted in place and showing the timber on which it is mounted broken away. Fig. 2 is an elevation of the gong mechanism with the gong portion thereof removed.

In detail, 1 represents a timber, board, or other object to which the base-plate 2 of the gong apparatus is secured. The base-plate consists of a fiat plate with an annular rim about it. Extending centrally from the fiat portion of the base-plate there is secured a rigid hollow arm 3, slotted at 4, with a square end over which the gong 5 is placed and held down by the nut 6, that is secured on the threaded end of the arm 3. The actuating means consists. of a push-rod 7, extending through the board 1 and base-plate 2 into the hollow arm 3 and carrying on its inner end a rack 8, Whose teeth protrude from the hollow arm 3 through the slot 4. A push-button 9 is secured to the outer end of said push-rod 7 and is protected and held from escape by the semispherical extension on the plate 10.

The slot 4 is long enough to permit the reciprocation of the rack 8 and push-rod 7. They are pushed in by the push-button 9 and returned by the spiral spring 11, which lies in the hollow arm 2 between one end of the push-rod 7, carrying the rack, and one end of the hollow arm 3.

The bell-hammer and the means for actuating same are mounted in a little frame that slips over the hollow arm and is readily removable therefrom when the gong 5 is taken 01f. This frame consists of a U-shaped plate 13, apertured at 14 to slip over the turneddown end of the hollow arm 3, and having secured to the lower end of the frame of such U-shaped plate and at a right angle thereto the plates 15. The two plates 15 are held in place at one end by a rigid bolt or pin 16. Near the other end of the plates 15 I mount a small shaft 17, which has rigidly secured to it a rod 18, carrying the hammer 19. In this drawing said rod 18 is shown bent, althou h that is not necessary; but said rod 18 must be so formed as to hold the hammer 19 in a position to engage the gong 5 when actuated.

I secure rigidly to the shaft 17 to actuate it a plate 20, extending at right angles and with its ends turned to engage, as in an escapement mechanism, a spur-gear 21, secured on the shaft 22, mounted in the plates 15, about midway between their ends, at least in such position that the pin-wheel 23, rigidly secured to said shaft, will be engaged by the rack 8.

It will be now understood from the forego- 8 ing description that when the push-button 9 is pushed in the rack 8 rotates the pin-wheel 23, and thereby the gear 21, and the rotation of the gear 21 rocks or oscillates the plate 20 and shaft 17, thus causing the vibration of the hammer 19. pushed inward the spring 11 pushes it back or returns it, and during such return movement the rack 8 continues to operate the bell mechanism, although reversing the movement of the parts; but the bell-hammer will be vibrated by the gear 21 when moved, regardless of the direction of its movement.

What I claim as my invention, and desire to secure by Letters Patent, is-

After the rack 8 has been 1. A gong mechanism including a slotted over the free end of said arm for mounting the hammer-actuating means, a gong secured to the free end of said arm, a push-rod slidably mounted in said hollow arm with a rack on one side extending through the slot in said arm, a spring for returning said push-rod after it has been actuated, a shaft mounted in said frame, a pinion secured to said shaft that is engaged and actuated by the rack of the push-rod, a toothed wheel secured to said shaft, a counter-shaft mounted in said frame, a bell-hammer secured thereto, and a plate secured to said counter-shaft with each end turned toward an d into engagement with said toothed wheel whereby said wheel when actuated will rock the counter-shaft carrying the bell-hammer.

In Witness whereof I have hereunto affixed my signature in the presence of the witnesses herein named.
